mysql5.6单实例安装(二进制)

1.下载二进制安装包
mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
tar -xvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

2.拷贝安装包和配置文件(如果没有特殊情况，将安装包解压放置在该目录)
cp -rf mysql /usr/local/mysql
cp -rf my5.6.cnf /etc/my.cnf

3.创建mysql用户
useradd mysql

4.添加数据目录
mkdir -p /home/mysql3306/mysql3306
mkdir -p /home/mysql3306/logs

5.修改目录权限
chown mysql:mysql -R /home/mysql3306

6.修改配置文件
socket          = /tmp/mysql.sock(socket文件存放位置)
datadir         = /home/mysql3306/mysql3306(数据文件存放目录)
server-id               = 12013306(设置serverid 命名规则:ip后两位+端口号)
port            = 3306(启动端口)
innodb_buffer_pool_size         = 1024M(innodb buffer pool大小)
*如果是核心节点单实例 配置成系统总内存的75%左右，如果不是核心节点则按照具体业务压力来设置

7.初始化数据库(确认2个OK)

10. OK
12. To start mysqld at boot time you have to copy
13. support-files/mysql.server to the right place for your system
15. PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
16. To do so, start the server, then issue the following commands:
18. /usr/local/mysql/bin/mysqladmin -u root password ‘new-password’
19. /usr/local/mysql/bin/mysqladmin -u root -h mysql5.6 password ‘new-password’
21. Alternatively you can run:
23. /usr/local/mysql/bin/mysql_secure_installation
25. which will also give you the option of removing the test
26. databases and anonymous user created by default. This is
27. strongly recommended for production servers.
29. See the manual for more instructions.
31. You can start the MySQL daemon with:
33. cd . ; /usr/local/mysql/bin/mysqld_safe &
35. You can test the MySQL daemon with mysql-test-run.pl
37. cd mysql-test ; perl mysql-test-run.pl
39. Please report any problems at http://bugs.mysql.com/
41. The latest information about MySQL is available on the web at
43. http://www.mysql.com
45. Support MySQL by buying support/licenses at http://shop.mysql.com
47. New default config file was created as /usr/local/mysql/my.cnf and
48. will be used by default by the server when you start it.
49. You may edit this file to change server settings
51. WARNING: Default config file /etc/my.cnf exists on the system
52. This file will be read by default by the MySQL server
53. If you do not want to use this, either remove it, or use the
54. –defaults-file argument to mysqld_safe when starting the server
